The Balboa Bay Club and Resort, a Rat Pack-era landmark, was supposed to be purchased by electric vehicles entrepreneur Winston Chung. But the deal was called off earlier this month, when Mr. Chung didn't come up with the money.

ORANGE COUNTY, Calif. — Winston Chung came to Southern California two years ago like a standard-bearer for the new China, a wealthy Hong Kong entrepreneur with visions of creating an electric vehicle industry by reviving struggling manufacturing firms.

Some dreams rolled out as planned. The battery scientist and clean-energy promoter bought control of four Southern California specialty vehicle makers. The University of California-Riverside renamed a building as Winston Chung Hall, saying that the $13 million he provided for green power research was the biggest donation in campus history.

But other ventures skidded off course, the biggest failure being a bid to step into the social spotlight by purchasing the Balboa Bay Club and Resort, a Rat Pack-era landmark where Republican power brokers mingled and John Wayne tossed back Conmemorativo tequila.

The $174.5 million deal for the combination yacht club and hotel and its sister Newport Beach Country Club was called off earlier this month. Chung never came up with the money as agreed, forfeiting what city documents show was a nonrefundable $4 million down payment.

"We were told he was having difficulty moving money out of China," David Wooten, chief executive of the clubs, said Monday. The deal could be revived if Chung produces the cash, but for now, competing offers will be considered, he said.

The Bay Club deal is one of at least three stalled ventures.

A seven-figure deposit Chung made in June on a Newport Harbor mansion once owned by actor Nicolas Cage is in jeopardy because he never came up with the money to complete the purchase.

And a plan to increase manufacturing at a Riverside motor home company, with the four-year goal of selling $5 billion in tour buses and campers to newly wealthy Chinese consumers, has been on hold for a year while awaiting approval from Chinese regulators.

Chung, 53, whose companies in the south China boom town of Shenzhen make products such as electricvehicle power trains and storage batteries for power plants, insisted early this month that the setbacks in Southern California would be temporary.

He blamed the delays on Chinese government reviews. Cash for the Balboa Bay Club and the waterfront estate was being held up by China's State Administration of Foreign Exchange, Chung said. His plan to sell U.S. motor homes in China was waiting approval from the country's Ministry of Commerce.

In telephone interviews, he said Chinese authorities had assured him that approvals would be forthcoming in time for him to buy the properties and to start manufacturing motor homes in March.

"One hundred percent certain they're going to go through," Chung said of his pending deals. A spokeswoman declined to comment further Monday.

Aaron Brickman, a U.S. Commerce Department official overseeing a program to stimulate foreign investment, said difficulties in getting funds out of China are not surprising. Unlike major Western countries, China controls the outward flow of cash as well as money coming into the country.

"China is still becoming comfortable with its own evolution regarding capital flow and investments," Brickman said.

The setbacks are bad news for Brad Williams, chief executive of MVP RV Inc., the Riverside maker of motor homes and trailers.

Williams said that about $30 million from a Chinese investment group that included Chung rescued his idled company in 2010. Among other things, the backing enabled MVP to buy a 24-acre Riverside manufacturing complex from bankrupt RV giant Fleetwood Enterprises.

But an additional $310 million in funding that Chung had pledged to jump-start production appears to be in jeopardy. At the very least, it won't flow until Chinese authorities approve the design of the tour buses and campers that MVP hoped to sell in China.

Williams, who had talked of generating 1,200 jobs in California's economically battered Inland Empire _ a deal the White House praised as an emblem of U.S.-China cooperation _ expressed frustrations in an interview last year.

"I'm dying to start hiring and I can't," he said.

Chung had expressed confidence that U.S. imports would find buyers among owners of private Chinese companies, despite high shipping costs, import duties and taxes on vehicles with large gas tanks.

"People who are above middle class will welcome this car for family trips," he said.

Michael Dunne, head of a Hong Kong consulting firm focused on Asian automotive markets, said an "outdoor culture" of getaways to the country is emerging in China, taking advantage of "thousands of miles of new high-speed multi-lane expressways that sometimes rival German autobahns."

Starting with pricey imports would establish "a sort of cachet or allure" in China, where the "wealthy set spend outrageous money on imported cars," Dunne said. "The Mercedes S-Class can retail for more than $350,000 after taxes and China is the largest market for S-Class Mercedes in the world."

During a visit to the Balboa Bay Club in October, the roly-poly Chung was exuberant, laughing loudly and seeming to bounce up the stairs from the yacht moorings to a conference room where he fielded questions from reporters.

Chung said he planned to buy or build a Southern California factory to manufacture lithium-ion batteries beginning this year. The goal is to create a cluster of Southland companies to make electric-powered tour buses, campers, yachts, limousines, shuttle buses and taxis. His target, he said, was annual sales of $3 billion.

Described in some news accounts as a billionaire, Chung chuckled last January when asked about his wealth. "Only God can know," he quipped. He listed his net worth at $533 million in an unaudited filing with the city of Newport Beach.

But the road to fortune has been rocky at times.

Chung was fired in March as head of Hong Kong-based Thunder Sky Battery, where he was a major investor and technical guru. The company claimed in a Hong Kong High Court lawsuit that he lied about his sales of the company's stock, launched competing businesses and otherwise violated his obligations to the firm.

Denying wrongdoing, Chung countersued in Shenzhen, where his manufacturing takes place. He charged that Thunder Sky, now renamed Sinopoly Battery Ltd., failed to pay his companies for batteries.

The dispute spilled into a Riverside County Superior Court lawsuit in August. Sinopoly Directors Miao Zhenguo and Jaime Che said they teamed up with Chung to invest in MVP, only to see him cutting side deals to the detriment of their partnership.

The suit said Chung promised Williams $310 million to burnish his reputation as a "green" investor, hoping to participate in Chinese President Hu Jintao's state visit to the U.S. last January. But, it contended, he's "never has taken any steps to make such an investment."

Court records show Chung sought to buy out his aggrieved partners and a tentative settlement of the Riverside suit was reached recently on undisclosed terms. The complex litigation in Hong Kong and Shenzhen is pending.

Until the recent setbacks, Chung was a deal-making dervish. In addition to MVP RV, his investments include Krystal Koach Inc., a Brea stretch-limousine company, and Balqon Corp., a Harbor City maker of battery-powered trucks and electric power drive systems.

Executives at the U.S. companies, where Chung holds the chairman's title, praised his leadership. They said he sets goals and challenges them, but doesn't micromanage.

"Every time I go back to him, he says: 'You're the CEO _ go figure it out,' " said George Gaffoglio, whose Gaffoglio Family Metalcrafters, a Fountain Valley manufacturer of concept cars and other specialty vehicles, won a $32 million investment from Chung in March.

At the Balboa Bay Club, the staff buzzes about Chung arriving in a Gaffoglio creation _ a battery-powered, stretched version of a London taxicab, painted bright orange instead of the traditional black.

Chung also pledged to build a clubhouse at the golf course, modernize 145 aging apartments that are part of the 15-acre Bay Club property and pay off $29 million in club debt. He even pledged to replicate the famed Orange County club in China.

To cement his offer to buy Cage's former mansion from the current owner, Nevada casino and gas station mogul Jerry Herbst, Chung said, he put down $1.7 million. He said he wouldn't lose that deposit because he plans to complete the purchase in March.

Other buyers could emerge, however. Robert Giem, the real estate agent with the listing, said the Newport Harbor waterfront estate had fallen out of escrow and is back on the market at $28.5 million.

Some China watchers said the problems were nothing new. Walt Disney Co. needed 12 years from the start of negotiations to break ground on a Shanghai theme park, said Marc A. Ross, spokesman for the U.S.-China Business Council, which represents American corporations.
